IPC: H01L21/027
Filed: 1990-10-31
Abstract: PURPOSE:To obtain a resist for ionizing radiation which does not require rewashing at developing and which is excellent in sensitivity and resolution by including in one polymer or copolymer substituents which decompose acids with other acids and generated substituents through light irradiation. CONSTITUTION:Substituents which are indicated by formulas I to and which generate acids each comprise a sulfonyl group or carboxyl group and these groups are decomposed by exposure to ionizing radiation into acids corresponding to the substituents such as paratoluene sulfonic acid, alkylsulfonic acid and acetic acid. The acids attack substituents indicated by the formulas IV and V and decompose the substituent of the formula IV as -OH+CO2+L and that of the formula V as -OH+CO+L into hydroxide groups (-OH) so that the polarity of a polymer or copoymer is greatly varied. Therefore the resist acts as positive type in the case of alkali developing and as negative type in the case of organic solvent developing using methyl isobutyl caine and anisole, etc.
